2018 charge tank question
« on: December 03, 2017, 02:32:29 AM »

Considering getting a 2018 SR with the charge tank (J1772 adapter). I believe the 2018 6kw factory charge tank is a new item, so what worked or didn't with the priors may not apply.

My local dealer wasn't sure, so I ask the wise members of this forum:

Regarding charging with campground 50 amp outlet with the 2018 charge tank: how much tech is needed?

Do I need a charge station like this:

Or, is just a cord with a NEMA 14-50 prong at one end and a J1772 at the other OK?

A few points:
  • No one has gotten their hands on a 2018 charge tank, and its presumable significant difference from the current/earlier charge tank are enough that it's not clear what is known for sure except that a 6kW capacity seems to be the new spec.
  • That 24A cable is not rated for the at least 30A that the new Charge Tank will draw to achieve 6kW (over 7kW with the onboard).
  • The difference (as far as the vehicle is concerned) between a NEMA 14-50 plug at an RV park and a J1772 station is the J signal, which indicates presence of power and capacity. So the only question is whether the charger requires a J signal to operate, and I'm going to guess the answer is "no".
So, I would just get a NEMA 14-50 to J1772 cable from Hollywood Electrics or other. But make sure it's rated for 40A, not 24A.

Thanks for the response.
Basic question here, I realize I must be missing something:
The 2018 charge tank is rated at 5.8kw according to Zero.
240v times 24A = 5.8kw.
If I have this right, then why would the 24amp clipper creek not be adequate to fully exploit the charge tank? Is the 5.8 number not the peak current draw? I ask because the clipper creek 24 amp is compact and light. Their next size up, 32amp is neither.

Does any of us have access to a 24amp clipper creek unit to try?

*Postscript* I recall there were some mounted on the wall at the Clipper Creek HQ...
